Step 1

For this tutorial, I used Photoshop CS3, a skull from Designious.com (you could choose to use a free skull though, such as Skull Vector Pack 1) and some hi-res flames images. The high-res image files are available to Psd Plus members in the download pack. Though non-members are certainly welcome to shoot your own flame photos or find some stock to use here, so you can follow along.

To get things started, create a new document 210mm by 290mm with a 100% black background.

Step 2

Copy (Command + C) and paste (Command + V) the vector from Illustrator to Photoshop as pixels.

Step 3

On a new layer create an ellipse filled with dark red (#4c0400) that surrounds the skull. Next, apply a Gaussian Blur of 250px (maximum value), and place that layer under the skull.

Step 4

Let's prepare the skull for the flames. Select the white color from the skull. (Select > Color Range) and fill it with an orange-yellow color(#f9ae31), except the teeth and mandible that will be filled with light red (#e82b19).

Step 5

Select the red area using Select > Color Range and then contract using Select > Contract > with 4 px, then and Delete.

Step 6

Select the yellow color. Next use a Brush with Toll on 250-300 px, Hardness of 0, Opacity at 10-15%, red for the color (d02207), and gradually color from the interior towards the exterior, until you get a skull with a bit of glow.

Step 7

Lets try to add some volume to the skull. Use the Eraser Tool with a diameter of 200px, Hardness of 0, and Opacity of 70%, and erase some of the red. Here we establish the lighter and darker parts of the skull so we can see some volume.

Step 8

Now double the Skull layer. Select the skull closest to the background and apply a Gaussian Blur of 8-10 px to create a glow.

Select the area under the nose including the teeth. Now grab a 80px Brush with a color of red (#d02207). Brush color on the right and left sides creating a soft gradient that ads depth to the lower part of the skull.
